The user can see current error information on Monitoring sub-menu on the LCD screen†
(see Figure 10.1-1); Table 10.1-3 shows the six detail information, which the user can examine
carefully using the hexadecimal number. When two or more errors occur at the same time, an
error code is given by the summation of the error codes. That is, when X and Y errors (e.g., X-
error-code '00000002' and Y-error-code '00000004') occur, the sum value '00000006' is screened.
